[Q] Problems charging/holding a charge/can't boot

Having massive issues right now. Last night I left my phone plugged in AC to charge and ran a sleep tracker app. Woke up this morning and found the phone dead. I tried unplugging and plugging again multiple times and managed to get the Red LED blinking then it went steady indicating it was charging. Turned the phone on but as if it wasn't charging anymore, it powered off within minutes. I managed to get recovery running and factory reset (running CM10). Same issue still there. I even tried leaving the phone in hboot and recovery to charge but after 10 mins the battery went flat again. Now I've just left the phone off and plugged into AC. The blinking LED came on again then went steady - but after 15 mins the LED light disappears. I just left it like that, now the phone tries to boot up but gets stuck at HTC logo. Also it is incredibly hot.
Any ideas? Really need help here.
Additional info, installed NFS: Most Wanted yesterday, tried playing but phone really overheated big time. Could that have cause the motherboard to fry? Just seems odd though cause it boots up fine, just won't stay on - can't even get past the initial setup wizard.
Also I would take it back to Vodafone AU but since I can't get the phone up long enough to restore to stock, they might find out I've rooted and thus voiding my warranty.
I had the same problem. I installed NFS MW and it drained my battery like help and when i tried recharging it it wouldnt charge
at all. Even when i pluged the phone on it wouldnt charge. Tried a different cable. For all it could be a adapter/cable problem.
That was what it was for me. I tried a different charger and it worked. If you are using a different charger, use something with 1A output.
If the led is blinking, it means that the battery is verryy low.
once your phone turns on, turn the airplane mode ON and display OFF and wait a few minutes before using the phone.
no luck

Yea, I tried using a different cable, even tried using my old iPod USB to wall adapter. No luck there, but I think I'm on to something now. Thanks anyway
getting there

Hey, yea I figured that much from searching around. Too bad it's such a big flaw. I couldn't sustain a charge at all when I was still on CM10. Couldn't even finish booting up and it would just die. Voltage was super low was my guess. Tried using the fastboot charging script (http://forum.xda-developers.com/showthread.php?t=1658084&page=5) and managed to get battery up enough to flash stock boot.img, did a nandroid restore to Stock ROM then flashed stock recovery. Seems to be stable now, in airplane mode and display off. Started up phone at 4% and now it's at 6% so fingers crossed :fingers-crossed: Thanks for the reply though - needing all the tips I can get!

[Q] Phone won't charge, but...

A few hours ago I noticed that the phone wasn't charging even though it was connected. So I did a few experiments: I put into into three different power outlets, I tried a different charger, I connected it to the computer but nothing happened (the computer didn't even recognize it). Then I decided to turn it off and try again, and these are the results: the screen turns on really often to let me know that it's charging, there's even the charging animation, but if I try to turn it on not only it isn't charged, but it doesn't seem to recognize the charger anymore.
There are a few other weird things, though: I use the XenonHD ROM, and once or twice when the phone was unplugged the battery icon was still "moving" as if the phone was charging, but the graph said that it wasn't. This probably is just a bug, but maybe it meant something.
My best guess is that the micro USB port is broken, but maybe you guys can help me with this?
Just like you said, your usb port is broken, propably a short circuit somewhere. But changing the charging port flex ribbon is very easy, even for a first timer (like I was/did a couple of weeks ago)

And now the phone charges if it's turned off... but it's not like I can keep it like this, so I'll take to technical support tomorrow. Do you think I should flash the stock ROM and/or lock the bootloader?

Note 2 wont charge when its shut off

Guys, i need your help. My phone suddenly died when i was charging it. Tried in the charger and was able to switch on, bat perctage is still showing as 30%. wHen i removed the charger it died again repeat the same thing and was stock in samsung logo. Was able to read one forum and owner experienced the same thing. What he did was used a diff bat. Tried it and it worked, so i purchased a msn hk replacement bat, however when i tried to switch the phone off while charger was plugged, it didnt work. No red led light, bat percentage dis not increase, no bat cahrging logo, so obviously it was not charging.i Inserted usb charger again and tried to switch off the phone but it just restarted. So the big problem is, every time that the bat is fully drained, i cant charge it using a usb charger, i need to use a universal charger 1st to boot the bat a bit then palce it back again so i can switch on the phone then use the usb wall charger. to ssummarize the problem, Phone Is charging as long as it is switched on but wont charge if its off and wont shut off while charging. Any one experienced the same thing? Is this due to the replacement bat? Need ur help guys, thanks
Up guys

Unexpected symptoms, need help assessing and figuring possible solutions

First time posting , I guess, usually I just browse through for info... but now I feel a bit in a dead end.
Spent a few days snowboarding with the phone in pocket, so exposure to cold subzero temp. lowest around maybe -10, only symptom during that period was camera started flickering showing purple lines but worked fine later on.
Also had trouble charging one night, as phone spent entire night being plugged in only to show it was discharging the whole time, and battery low in the morning, couldn't get it charge even after cleaning port making sure its clean and dry.
Phone ended up running out juice and powering down completely... it didn't respond for hours (tried different chargers) but than suddenly the power bank I use showed it started drawing about 9V and 0.1/0.2A for some time and it slowly started drawing more power and charging to 100% took more time then usual...
Next time I tried charging it when it became low around 20% it wouldn't charge from the wall charger or battery charger.
Tried a lot of resetting, rebooting, but the battery just started dropping really fast each reset.
Plugged it in and tried the volume up/down, power button reset but all that did was a multiple resets and still wouldn't draw charge from anything.
In the end it just stopped responding to anything.
I would show a few orange flashes when I plug it to something and than stop.
Tried leaving it plugged in all night but nothing. Leaving it alone for 3 days also did nothing.
Then it stopped even showing the few orange blinks.
Current status:
Plugged it into computer usb and started showing orange flashes, decided to leave it plugged in.
Showed on screen the battery and 0% after a few min. Screen brightness increased after 20min.
Now its been 3h and its still only showing 0% for battery and flashing the orange light every few seconds, nothing else.
Will go to sleep now and leave it plugged in computer all night.

Have you tried a different USB cable & charger?
There have been numerous reports in these forums concerning charging issues with the device. If you've cleaned the USB port on the phone and have tried multiple USB cables and chargers, then most likely your battery is the culprit and needs to be replaced.

In a lot of cases they managed to restart the phone...
Yes I did that. Phone is still showing 0% battery after being plugged in computer usb, I find it funny how it wasn't responding at all to the wall chargers. Now for the question of the day, can I have the battery replaced without losing data? I asked a service center that kinda could be a HTC representative but cannot confirm it and they insisted that they have to do factory reset.

Can you charge the phone up and get the phone to boot to TWRP? If so you can mount your phone to your computer and back up all of your files on your internal storage to your computer.

I don't have TWRP but I just did manage to enter the stock recovery? and its just sitting there not really charging up but using 9V and 0.4A to stay powered up in that mode.
Can you tell me if I go to service center to get the battery changed will I lose all data by default of that process?

I wouldn't think that merely changing the battery would cause you to lose your data, or why they would do anything to your phone that would wipe your data from the phone.

Alright, that was my primary concern, thank you. The service sector where I live is pretty bad, and they do stupid stuff, follow stupid rules.
Update: I switched through a couple of chargers, and tried going into recovery after which I initiated a restart, phone booted normally and showed 24% battery, now is connected to original QC 3.0 ... and charging up, but stopped after 1%, I unplugged it and plugged it again and it continues to charge now with steady orange light? this is really nerve wrecking... what is the real issue? battery, charging port?
My goal is to try to charge 100% back up everything and then I can send it service.

help, my phone stops charging

hello guys,
i need help figuring what is wrong with my phone. it cannot be charged right now, even when plugged in with charger,
the charger and cable i used dont seems to be the problem as i tested with my other phone too.
i have tried changing charging port and battery, but it still didnt solve it. so here i am asking for your opinions.
last week, my phone stops charging when plugged in and the battery wont go up when charged, i tried using same charger and cable to charge my other phone but those didnt seem to be the problem. after that, my phone eventually ran out of battery and died.
then, i thought my charging port has problem, so i buy new one and change the charging port.
but that didnt not solve my problem, as my phone did not even boot when plugged in and when i tried to charge it after that.
then, i assume it was my battery that has problem. so i bought new battery, fortunately, the new battery came in with 50% of battery juice. but after i try to charged it, the problem still there, the phone still cannot be charged.
this time, i checked with the ampere app for my charging status and found that when plugged in, initially the phone is charging, but after few seconds, the charging stops and it will repeat the charge-stop charge cycle. this is also visible with my charging led light.
however, i dont remember if this charge-stop charge cycle was there initially last week, i only remember it just stops charging, so i didnt know whether this is another problem or the same one initially.
things that i have also tried
1. i also tried changing the charging port to the old one and it didnt do anything, same as im using the new charging port. the problem still there.
2. i also tried using usb file transfer to test whether the charging port are problematic overall or just the charging part is problem. my usb connection has no problem as i can steadily transfer file for few minutes without disconnecting. so i assume my new charging port has no problem then.
3. i also tried flashing stock rom as i thought maybe kernels and stuff from custom rom messing things up. but it also didnt solve it.
4. i also tried turning the phone off and charging it, the phone boots up to charging screen, but the battery keeps dropping instead.
i dont really mind if this phone cant be saved anymore, i already backup important stuff from it, i just wanted to try fixing it for fun now.
also, english is not my first language, sorry if there are parts that is hard to understand.
Maybe some partitions are corrupted(like persist or any other)... search on xda how to flash those partitions. And try flash full MIUI fastboot ROM. Khmm if this doesn't work than I'm out of ideas. You can buy charger for battery only, for playing around until you gonna find a fix. Better than buying new one.
Good luck.
